Java SSH Client API

With over a decade of production use, the Maverick Legacy Client has long been the definitive solution for total SSH compatibility on the Java™ platform. Today our Java SSH API is used by many clients from all walks of industry, these include defence contractors and other high-technology vendors specialising in VPN software and Internet hardware.

Maverick Legacy Client is a Java library that enables software developers to utilise the Secure Shell (SSH), Secure Copy (SCP) and Secure File Transfer (SFTP) protocols within their own Java applications. This library provides the ability to integrate an SSH client into your own application, allowing outgoing connections to be made to SSH servers so that files can be transferred, commands executed or ports forwarded for other networking applications. If you want to build your own SSH server you should consider our Maverick Legacy Server product.

Designed as a successor to J2SSH, a popular open source Java SSH library, and written by the same author, Maverick Legacy Client was built from the ground up to provide the highest possible performance and to add support for the SSH1 protocol. The API now has a mature and stable code-base and has been integrated into many mission critical systems at countless Fortune 500 companies.

Why should I purchase?

With all security related products it’s important that you keep your software up-to-date
and inline with current specifications. Over time security products can become vulnerable
to new exploits. To combat this new or stronger cryptography algorithms are introduced; leaving
the older algorithms as well as your software more vulnerable and open to attack.

With our commercial licenses you get our SSH expertise at your fingertips. When specifications change or new vulnerabilities are found we are able advise our customers on the best strategy to mitigate the risks and provide product updates within hours.

What do I get?

Our commercial licenses include 12 months support & maintenance as standard. Giving
you get the benefit of quick turn around bug fixes, new features, stronger cryptography
and unlimited support enquires with an SSH specialist ready to answer your questions.

J2SSH Maverick has, until recently, only been available under a commercial licensing agreement. With the release of our 1.6.x branch and in honour of the 10th anniversary of J2SSH Maverick’s first commercial release, we have released our legacy 1.4.x branch under the LGPL for use in open source applications.

We now have the following license options:

LGPLv3 License (without support)

We have released our base SSH2 implementation under an open source license (LGPLv3). You may use this in both open source and commercial applications, however support is limited to community channels.

Commercial License (with support)

We continue to license our full product stack under a commercial license with unlimited email support and regular product updates. These licenses include support for both SSH1 and SSH2 protocols along with additional utilities not available in the open source edition.

The API is now under Long Term Support (LTS) and will continue to be commercially supported for the foreseeable future. There are 2 separate branches of the software:

1.4.x

This is branch is only available to commercial customers and whilst still maintained it is not receiving new features, only security updates and critical bug fixes. This version will reach End of Life (EOL) on 31st January 2018.

1.6.x

This branch will only receive security updates and bug fixes for the duration of its lifetime. It is recommended that all customers upgrade to the latest release on this branch as soon as possible. This version will reach EOL on 31st December 2019.

1.7.x

This is the cutting edge development branch that will receive new features, security updates and bug fixes. It is backwards compatible with 1.6.x with the exception of deprecated APIs that have been removed and with the minimum Java version raised to 1.7. This is now our stable, production ready branch.
